14 claims.

This invention relates to a new and improved apparatus for forming self-fittingl ends .on candles. f

The main object` of my invention is to provide a device for speedily andl efciently forming the ends of candles into a shape Iwhich willv make them self-fitting when they are inserted in candle sticks and which will allow them to conform to candle sticksor holders of different sizes within certain limits. ,K p f y Another object" 'is to l provide an apparatus which may be used `as desired to form the ends of candles of4 different sizes.` Y

Another object is to provide an apparatus by the use of whichrthe ends of 'a' plurality of candles may be'shaped simultaneously. y'

Other objects and advantages lrelate to the size, shape, and arrangements of parts, all as will more fully appear from the following description taken in connection with the accompanying drawingsyin whichz- Figure 1` is a vertical `longitudinal section through my device. I Figure 2 is a section jon line 2 2 4of Figure 1.

Figure 11 is afsection on line 11-11 of Figure 10.

My device, comprises a main frame 1 in which is journaled a hollow steam box 2, here shown as square in cross section', which steam box 2 may be made of iron or other appropriate heat conducting 1naterial. In one .endrof steam box 2 is inserted a feed steam pipe 3, an appropriate stuiiing box Lilbeing provided. In the other end of steam vbox 2 is inserted an exhaust steam pipe 5,. an appropriate stud-lng box 6 being provided.

In one of the ends of steamY box 2 is provided an aperture 7 into which may be inserted the end of a pin 8 which is slidablymounted in frame 1. I n the embodiment hereshown, four aperbe locked in any desiredone of four positions with relation to frame 1. When'it is desired to change the position of steam box 2,"the pinSis retracted to permit steam box 2 to be rotated in its bearings to bring'it to the desired position when the pin 8 is then moved inwardly into regis-,- tration with anv aperture 7. .l l

On each'of the four outsideV faces of the steam box 2 I secure a plurality of dies hereinafter to be described. Any number of dies may be provided and I have here kshown four rows of dies on each face. On Figure 2 I have indicated four rows of dies in heavy lines and on the other three faces I have indicated four rows of dies in dotted lines.

flutes 9. The fiutes 9 being' comp'aratively'think in cross section will flatten out upon lthe insertion ofthe candle into a candle stick or. holder to conform to the shape ofthe inside of such holder and when the candle is bottomed in the holder it will t snugly and tightly therein.

The dies 1o used to form the ends of the candle 8 are similar in shape so that afdescription of one will rbe a description of the others.

The die 10 comprises a main body 11 and a top 12. -The main body 11 is approximately cylindricalin form and has its upper end castellated as shown at a on Figure 9 to provide av plurality of circumferentially spaced laterally outwardly extending slots 13. Y

Although they may be differently. arranged if desired, I vprovide on the outer face of the main body 11 and in. communication with alternate slotsy 13, a plurality of longitudinally extending grooves 14. Adjacent the bottom of main body 11 is provided a circumferentially extending Vgroove l15. The grooves 14 are deeper than' the groove 15 forV a purpose hereinafter to be described.

As perhaps may best be seen from Figure 6 I provide in the bottom face of main die 11 a plurality of spaced outwardly extending grooves As perhaps may best be seen fromFigures 3 and 4, the inside of the main body 11 of the die 1 10 is tapered downwardly and inwardly from the top to the bottom' sothat the-aperture' in the bottom is less in diameter than the aperture in the top.

In the tapered inner face of the main body 11 I provide a plurality, in this case shown as seven, of slots 17 which are in spaced relation and which preferably become gradually deeper as they approach the bottom of the main body l1. Although not essential, I prefer to form the slots 17 in such a way that they will have curving sides which merge into the adjacent portions of the main body 11.

The top member 12 has a collar 18 with an internal shoulder 19 and is adapted to nt on the castellated end of the main Vbody l1, the shoulder 19 holding it in such a position that the grooves 13 are left open. The upper portion of member 12 flares outwardly and in this case is shown as square in form although it could be of a different shape if desired. The function of the member 12 is to guide the candles to be formed into the main body 11.

As a convenient means for securing the dies on steam box 2, I provide a pair of straps 20 which have a plurality of opposed semicircular out away portions 21. In the straps 20 I provide as many cut away portions 21 as there are dies 10 to be secured. These straps l0 with the cut away portions 21 are of a size and shape to encircle the main body 11 with the straps 20 seated in the groove 15. With the parts in this position, the straps 20 are secured to the steam box 2 as by screws 22 thus locking the dies 10 to the steam box 2 with the bottom of the dies 10 in physical contact with the steam box 2.

On each outer face of the steam box 2, I provide a pair of spaced laterally extending grooves 23 two for each lateral row of dies which extend from side toside of steam box 2and which gradually increase in depth from one side of the steam box 2 to the opposite side thereof. The grooves 23 are so positioned that they are beneath the opposite edges of dies 10 and in communication with grooves or channels 14 when the same are in position on steam box 2.

Operation When it is desired to use my apparatus to form the ends of candles, the steam box 2 is rotated to bring into the top position the dies of the appropriate size to receive the ends of the particular candle it is desired to form. Steam is then introduced into the steam box 2te heat the same and the dies 10 being of an appropriate heat conducting metal and being in physical contact with steam box 2 will in turn become heated.

The candles to be formed arethen suspended in spaced relation above the dies 10. The lower endsof the candle are squared oir and then they are allowed to move by gravity down into the dies 10. The dies 10 being heated, parts of the butt end of the candle will melt as it descends into the die 10 and this will cause the end of the candle to conform to the shape of the inside of the main body 11 of the die l0., When the candles have seated in the dies 10 they are withdrawn therefrom and allowed to cool.

During the forming operation, the melted wax escapes through the slots 13, grooves 14, and grooves 16, the larger part of the same entering the grooves 23 and running downwardly therein to now off the face of the steam box 2. The grooves 14 being deeper than the groove 15 in which the straps 20 are seated permits any melted wax flowing down the grooves 14 to pass downwardly beyond the straps 20.

This operation is repeated until the desired number of candles have been formed.

The dies 10 being heated, they are self-cleaning so that the slots 1'7 are always clear at the beginning of the forming operation.l

Although I have here shown a particular way of heating the dies 10, it will be understood that other means may be employed for holding them at the proper temperature.

It will also be understood that although I have here shown a particular arrangement of the dies 10, that such arrangement may be varied as desired, for although I have shown an described a specific structure and form and relation of parts thereof as an exemplication of an embodiment of my invention, I do not desire to restrict myself to the exact size, shape or arrangement of parts as various changes may be made in the scope of the appended claims.
